Design Information
5.1 Overview of the BTX Reference Design
The reference thermal module assembly is a Type II BTX compliant design and is
compliant with the reference BTX motherboard keep-out and height recommendations
defined in Section 6.6.
The solution comes as an integrated assembly. An isometric view of the assembly is
provided in Figure 5-4.
5.1.1 Target Heatsink Performance
Table 5–1 provides the target heatsink performance for the processor with the BTX
boundary conditions. The results will be evaluated using the test procedure described
in Section 5.2.
The table also includes a T
A
assumption of 35.5 °C for the Intel reference thermal
solution at the processor fan heatsink inlet discussed in Section 3.3. The analysis
assumes a uniform 35 °C external ambient temperature to the chassis of across the
fan inlet, resulting in a temperature rise, T
R
, of 0.5 °C. Meeting T
A
and Ψ
CA
targets can
maximize processor performance (refer to Sections 2.2, 2.4. and Chapter 4).
Minimizing T
R
can lead to improved acoustics.

NOTES:
1. Performance targets (Ψ ca) as measured with a live processor at TDP.
2. The difference in Ψ ca between the Intel Core™2 Duo processor E8000 series with
6 MB cache, Intel Core™2 Duo processor E7000 series with 3 MB cache, Intel Pentium
®
dual-core processor E6000, E5000 series with 2 MB cache, and Intel

Celeron
®
processor E3000 series is due to a slight difference in the die size.
